A phase change memory with an operating current that can be gradually increased or gradually decreased. The phase change memory has a phase change storage element, a transistor, and a control circuit. The transistor is operable to adjust the operating current flowing through the phase change storage element. The transistor has a first terminal coupled to a voltage source, a second terminal coupled to the phase change storage element, and a control terminal receiving a control signal from the control circuit. The control circuit is specially designed to limit the transistor in a linear region. |
